A320 wing streak
Today I was doing a flight from Rapid City South Dakota to Billings Montana. When I was taxiing to the runway I noticed these black streaks on the leading edge of the wing and under the fuselage. I was wondering if anyone else had noticed this before and knew the reason for it.
The two things I could think of to explain the black streaks was that this was added on purpose to make the aircraft look a little more “worn“, The second thing I thought of was that perhaps this was a glitch or mistake by the developers.
If someone has any more information or ideas I would love to hear them, thanks!
P.S. this is my first time creating a topic and would be open to hearing feedback on how I did. 😉
